SPRINKLER.

SPECIFICATION forming part of Letters Patent N0. 425,340, dated April 8, 1890.

Application filed February 5, 1890. Serial No. 339.309. (N modelil To etZZ whom it may concern: tubular in line with the standard A, and its Be it known that I, JOSEPH OsWALD,a citilower end is screw-threaded on the inside, so zen of the United States, residing in the city as to be easily screwed upon the threads not 5 and county of San Francisco, State of Calithe standard.

Fig. 2 is a view showing the standard, The head has holes K made transversely the inverted tapering head, and a sectional through it to allow the water to pass out into view of the rotary sleeve. the arms of the rotary sleeve, and in order to In thema-nufacture of lawn-sprinklersof that facilitate the passage of the water I prefer to 80 class having a vertical standard and a rotary .form a groove or channel around the head at head with arms, upon one side of which jetthis point. The holes in the head are apholes are made for the escape of the water, so as proximately in line with those in the sleeve to give the sleeve a centrifugal rotary motion, and the arms. The upper end of this sleeve various methods have been employed to proabuts against the fixed flange or top F of the 8 5 vide an easily-running head, and at the same head E, and it is held in place by means of a time to prevent or compensate for wear which nut M, which screws up from below upon may take place. screw-threads N, formed upon the exterior of In my invention, A is the vertical hollow the lower end of the head E.

This head is hollow or By means of the nut M, which screws upon the bottom of the head, the sleeve may be raised or depressed, so as to change its fit upon the head. \Vhen water is admitted under pressure into the standard, it passes out into the oentrifugally-acting arms of the head, and the tendency of the water-pressure being to lift the sleeve it will be forced up against the washer at the top, and will thus always keep a close joint at this point.

I am aware that vertical standards having centrifugally-rotating heads and perforated arms have been employed as sprinklers, and I am also aware that such heads have been fitted upon the upper end of the standard, so as to slip on from above. I do not claim these devices, broadly; but

What I do claim as new, and desire to secure by Letters Patent, is

1. In a lawn-sprinkler, the hollow tubular standard having its upper end screw-threaded,

the independent head in the form of an in-- verted frustum of a cone removably fixed upon the standard and havinga flange or cap integral with and proj ecting around its upper and larger end, in combination with a-sleeve having the perforated radial arms projecting from its sides, the interior of said sleeve becap at its upper end and water-escape openings through its sides, as shown, in combination with the sleeve having the radial perforated arms and the interior fitted upon the inverted conical head, a nut screwing upon the lower end of the head and supporting and adjusting the sleeve from below, and a removable Washer fitted between the upper end of the sleeve and the projecting flange of the head, substantially as hereindescribed;

In witness whereof I have hereunto setmy hand. Y
